SLEIGH.

Application led May 24,

, This invention relates to a propellable sleigh, `ofl the type usuallyreferred to as a bob-sleigl1,and its principal object isto proL vide 4adevice of thischaracter havingzmeans tolimpart motion thereto.

5L-further object is theY provision ofa novel steeringmechanismfand'adequate brakingfapparatus. l

The sleighl is built on practical lines and will be found both sturdyandV reliablein I use;4 Y y The .aforementioned objects, together withother features and advantages willbe-fully described in the followingspecification, and

illustrated in the accompanying drawings, in

which:

Referringffirst toFig. 1 ofthe. drawings;

the sleigh is constructed as follows: y A Am'ain'loody 10is supported ona sled 11 Vand has its lower frame element 12 extended forward beyondthe said main body structure. Pivotally secured' to the said forwardextension is a steering sled 13. This is vcon- 'i nected by means of thebolt Y14 and the nut 15. An auxiliary body 16 is mounted on the saidsteering sled. I 1

Apropelling mechanism is built Vinto the Y main body and is of thefollowing construction: Propellers as shown at 17 and as seen at 17 and18 in Figure-2 having rear extending toothed members as that shown at19,

Vare provided with slotted portions as that 1 shown at 20, which areadapted to slide on aV supporting bar 21.v YAt; their upperextremi- 0 assho-wn at 22, to rocking levers asV thatf ties, these propellers arepivotally attached shown at`23; there being two of 'these con-` Vdownward 1926: serial no.111,1 02.l

This causes the propellers tov slide back at adownward angle 'and to grip the snow, or ice'with the" teeth as shownVvat 19,and the continued pressure drives the sleigh forward.v The bar24 is pushed for ward and again drawn back in the saine maiiner asbefore.` This repeated vaction propels thesleigh in a forward direction.`When necessary to check the speed, as in going down hill, the brakeshoe 26 is forced by'v a backward, .pull ,on the leverBO. 'p f y vrThesteer'sinan guides the sleigh, by turn ing the hand wheel, whiclnactingvthrough a 'tension on one cable and acorresponding relaxation of theother and ldra-ws the for Vthe :bevel gears turns the drum. Y Thiscauses 11ol Y ward part of the steering sled over to theside of thetight cable. -This, in greater,

o1" less degree changes the course of the sleigh as desired.

...In Figures 5 and 6 I have shown an ar'- rangement of the invention inwhich thev Y rocking levers are actuated by a. motor drlving mechanisminstead of the hand bar.

In this arrangement; a motor of suitable 'design 50 is mounted inthemain body and is connected Vby means of the pulley 51 and the belt 52 to,av drive. wheel 53.

which" is mounted the connecting rod 55 which, atits forward endis'secured by a sultable vbearing member to the shaft 22,

'Y The engine clutch is controlledby the lever position.

' in'rlnotor cycle construction and the like.

The Carburettor land magneto are shown at ,60 and 61, and the gasolinetank at 62.

The actionof this driving mechanism is Y' A.similar to that of the firstdescribed, except s thatthe kconnecting rod'actuates the proa Y pellerlevers.KV

The propeller-as so used in thisform is provided with an L member 7 4 which toothedggportion ofthe'baras shown at`7l.

This drive vwheel 1s provided with an eccentric 54 o n is connected totheV is slotted as shown at 75 and engages the stud 76 on which it isfree te move as required.

lVhile I have shown vthe preferred forms of the invention I do not wishto be limited to the exact construction as illustrated, but claim therightto such minor modifications as may come'within the scope of theappended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is as follows:

l, In a sleigh, a body structure ,comprising pivotally connectedrearward and forward sections, a front and rear seat in vsaid respectivesections, meanscontrollable by the occupant of said forward seat forguiding" the direction of the movement of said sleigh, a lever pivotallymounted on said body operV -able by the occupant of said rearward seat,

a slidable rod pivoted at one end to said-VV lever, the lowerportlon ofsaid rod being'l curved to render the end portion thereof substantiallyparallel to the longitudinal aXis of said rearward body section, and aplu- V rality of teeth on said'endportion adapted to dig into thesurface upon which said sleigh rests to Vretainsaid rod substantiallyfixed while urging said sleigh forward.'

.2. In a sleiglna body 'structure mounted on runners, a shaft disposedlaterallyv ofl and rotatively mounted in said body structure, rockinglever journaledat one endg-on said shaft, a handle member joining saidrocking member at the upper end thereof, rods slid- I* ably mounted onsaid body structure and pivotally attached to said levers intermediatethe ends thereof, the lower portion of said rods being curved, and teethon-V the lowermost edge of said curved portion adapted to engage the iceand snow upon which said sleigh is supported,said teeth being adapted toindividually andsuccessively dig into said ice and snow when the rodsareforced rearwardly by movement o f said levers.
